Papua New Guinea's foreign minister has denied reports that the country is in negotiations over a second Australian facility to process asylum seekers.

One media outlet has reported talks were underway for a second facility near Port Moresby's airport.

Foreign minister Rimbink Pato says the report is inaccurate and PNG's priority is to construct a permanent facility on Manus Island.

"At this point no particular site has been discussed or chosen," Mr Pato said.

"We're looking to speed up the process of construction of the Manus regional processing centre."

Mr Pato says a permanent processing facility on Manus Island would have to be completed before talk of a second facility can begin.

"We don't want to run away from our international obligations," he said.

"Our focus at this point in time is the regional asylum processing centre on Manus Island."

Mr Pato says a joint effort to process asylum seekers on Manus Island by Australian advisors and Papua New Guineans on the facility are underway.

"Our Cabinet has approved a legal structure within which the processing will occur to determine the question of whether or not one is entitled to refugee status, so that the issue of resettlement in a third country can take place," he said.

He says there is also an appeals process in place as part of the processing.

"The legislative process requires if anyone is dissatisfied as to the determination of any of the issues or the considerations that must be looked at then the process review requires that I will obviously reconsider the matter," he said.

Mr Pato says there are currently up to 200 asylum seekers at the processing facilities and he is open to taking on more in the future.

"Once the permanent facility is developed then we can look at the expansion of the number of asylum seekers who'll be there for processing under our legal system," he said.

"We are always there ready and willing and able to assist our good friend- the government and the people of Australia."
